The Y2K Guide to the R-390A is Absolutely Wonderful, and Absolutely
Free. And the manuals also are available on the web. This group is the
best place in the world for advice, hints, and kinks. Just be a bit
careful about grabbing the B+. I don't work without a safety observer,
but YMMV.

There are better receivers, but not many, and the the sand-state 
better receivers are a bit fragile around the front-end.

You list just about everything you need, except for sidecutters and 
Bristol screwdrivers. 

Bits and pieces are available from Fair Radio and other sources, so 
you can replace most anything you fsck up, and it's nice to have 
spares -- but it's not all that hard to work on, either, and it's 
pick-up-one-end-and-drop-it-and-the-CW-tone-stays-constant stable.
Think of it as the Nikon F of radio receivers. 

So: Amen! Dig In!
